Merge pull request #206 from sysms/master

Completed german translations.
Icon update; reamake of the *.svg scalable icon, and pause+recording variant, with export to all *.pg size. The icon now doesn't show big SSR letter nor too saturated colors. It fix a issue on desktop with rich icon theme ; the SSR icon was not looking too good on them. Credits goes also to the public domain work of mrallowski on openclipart.org for the base of the lens icon gfx.
icons gfx : tweak on the design (red lens for record, and grey for pause with grey color ), and also cleaning; vacuum defs, and SVG file using plain SVG spec, for easier export and manipulation of the scalable by systems of other software.
